Cassini has discovered a number of new moons around Saturn, including several near and even nestled among Saturn’s rings. It has also taken spectacular data of many of Saturn’s known moons, including Titan, Rhea, Dione, Thetys, Hyperion, and Enceladus. Astronomers used Cassini to discover that Enceladus has liquid water below its surface, and has huge geysers that spray icy frost into the space around Saturn.
